Overview

The Fazenda mine is located within the Maria Preta mining district in Bahia State, Brazil, about 180 kilometres northwest of the state capital city of Salvador. The mine covers approximately 63,400 ha, and is accessible by air and road. The Fazenda mine has been in operations for more than 30 years and is primarily an underground operation being mined by conventional retreat longitudinal longhole open stoping with a 1.3 Mtpa carbon-in-leach (CIL) milling facility.

Geology and Mineralization

Fazenda is located within the Rio Itapicurú Greenstone Belt (RIGB), a 100 kilometre long, 60 kilometre wide north-south trending volcano-sedimentary belt situated within the São Francisco Craton. Fazenda is an epigenetic, structurally controlled, and hydrothermally altered Precambrian quartz vein hosted lode gold deposit that has been subjected to greenschist facies metamorphism. The main mineralization is in the form of sulphide-bearing quartz veining, and these multiple vein systems vary in true width from 1.5 to 40 metres and horizontal mining widths vary from a minimum 3 to 40 metres.
